Pressure sensitive adhesive film for optical parts
PD
PANACLEAN is an extremely transparent and durable pressure sensitive adhesive. It is perfect for lamination of optical parts.
Features
- Excellent transparency.
- Since tackiness is extremely high, adheres strongly after lamination.
- Excellent durability. No yellowing by heating and humidification.
- Little oozing from the end and low contamination of other material.
Main applications
Compounding of flat panel displays and other optical functional films

*1Measured when laminated to glass. (Total light ray transmissivity of glass : 95.1%, haze : 0.3%)
*2Peeling angle: 180°, peeling speed: 300mm/min
*3Glass is used as the durability test adherend and test is performed for 1000 hours under each condition.
※For measurement items other than separator release force, measurements were made after first re-sticking the light release separator side to high transparency PET film (100μm).
※The above are measurement values and are not guaranteed.
